Marc,

I get RX-0: FIFO overflows in listen-only mode (back-to-back burst of
the single other node).
The SPI peripheral does not use DMA :-(.
Do you have, by accident, some freescale SPI fixes lying around?

It's not the biggest problem on my side, but is proves the system not
being guarded against load.

Kurt
